Application filed August 28, 1918. Serial No. 251,813.

To aZZ- whom it may concern:

Be it known that I, Morrnn CLAR, a citizen of the United States, residing at Fort Morgan, in the county of Morgan and State of Colorado, have'invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators, for motorvehicles, particularly to those of the tube type, and has for its object the provision of a radiator substantially all of the component parts of which are held in assembled relation by means of a plurality of stay rods, removal of which permits disassembling of all the different parts of the radiator whereby access may be readily had when repairs are necessary.

An important object is the provision of a radiator of this character which is so constructed that the tubes are disposed in clamped relation between the upper and lower tanks of the radiator without the use of solderor other securing means other than the stay bolts employed for holding the upper and lower tanks in assembled relation.

A further object is the provision of a radiator of this character in which the radi ating fins as well as the tubes may be quickly and easily removed and whereby the radiating fins may be removed without disturbing the position of the tubes.

Another object is the provision of a radiator of this character which will be simple 33 of Fig. 1.

and inexpensive in manufacture, easily assembled and disassembled, highly eiiicient and durable in use, which will require but little labor for repairing, and which will be a general improvement of the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fullydescribedand claimed and illustrated in the accompanying drawings in which Figure 1 is a front elevation of the radiator entirely assembled.

Fig. 2 is a similar view of the radiator proper with the outer incasing shell shown in section and with the radiating fins removed.

Fig.3 is across sectional view on the line Fig. 4 is a side elevation of the radiator proper with the outer shell removed.

Fig. 5 is a detail view of the upper tank illustrating the connection of the overflow pipe, the tank being shown in section.

Fig. 6 is a detail cross sectional view through the lower tank. t 51g. 7 is a bottom plan View of the lower Fig. 8 is a bottom plan view of the radiator supporting plate.

Referrlng more particularly to the drawing, the numeral 10 designates the outer shell of the radiator which may be of any desired contour and which is designed to serve as a protection for the radiator'proper which is designated by the numeral 11. The radiator proper 11 is shown as comprising upper and lower tanks 12 and 13 respectively between whichextend and with which communicate the vertically disposed spaced tubes 14. This arrangement of parts is old and well known and no novelty is claimed for the general arrangement. I

In carrying out my invention I form the upper tank 12 of two sections or pans, the lower one 15 being formed preferably as a casting and having an open top in which is telescopically received the upper pan 16 which is soldered in place at its line of.junc-' ture with the lower pan. The upper pan 16 is provided with the usual filling neck 17 which extends through the shell 10 in the usual manner. Throughout its periphery,

the lower pan '15 of the upper tankl2 has formed thereon a plurality of'spaoed lugs 18 which are apertured as shown for a purpose to be described. Etctending downwardly from the bottom of the lower pan 15 and cast integrally thereon, is a plurality of nipples 19 within which are reduced extensions, 20, these members being provided with a bore 20 communicating with the interior of the upper tank.

The lower tank 13 is very similar in construction to the upper tank 12 and is formed in two sections, an upper pan 21 which is formed preferably of cast metal and a lower pan 22 which is .telescoped into the pan 21 'and soldered thereto at its line of juncture tion of vertically disposed stay rods 27 which extend also through the apertured lugs 18 and which are provided with clamp-- ing nuts 28.

The water tubes 14 are of ordinary construction and are formed preferably of copper and have their ends outwardly flared as shown to provide flanges 29 which are adapted to be disposed within the space between each nipple 19 and its reduced portion 20. This space between each nipple 19 and its extension 20 is partially packed with any suitable acking material 30 which is engaged by tie flanges 29 so that a tight joint may be formed.

The radiator is assembled by placing the tubes 14 in position upon the lower tank 13 with the flanged lower ends of the tubes disposed within the spaces between the nipples 23 and the extensions 24 and with the extensions 24 entering the tubes. The upper tank 12 is then placed upon the upper end of the tubes 14 with the nipple extensions 20 disposed within the upper ends of the tube and the tube flanges disposed within the spaces between the nipples 19 and the extensions 20. The stay rods 27 are then inserted through the alined lugs 18 and 26 and the nuts 28 are applied to the threaded ends of the stay rods and screwed firmly into place so that the upper and lower tanks 12 and 13 will be drawn together into clamping relation with the ends of the tubes 14. The provision of the packing at the ends of the tubes 14 insures the formation of water tight joints so that all possibility of leaks will be prevented.

The lower an 15 of the upper tank is of course provided with a pipe 31 and the upper pan of the lower tank is provided with a pipe 32, both of these pipes being of ordinary construction and afiording means whereby the radiator may be connected in the water circulatory system of the motor. The pipe 32 is provided with the usual drain cock 33 so that the radiator may be drained when necessary.

In order to reinforce the lower tank so that any possible buckling thereof will be prevented, I provide a supporting plate 34 disposed against the bottom of the lower tank and provided with a depressed portion 35 for the accommodation of the :pipe 32, this depressed portion 35 beingprovided with a recess 36 for the accommodation of the drain cock 33.

lower pan 15 of the upper tank is provided with a downwardly extended nipple 38 into This plate 34 'is of greater width than the bottom tank 13 for a the bore of which is threaded the lower end of an overflow tube 39 disposed within the upper tank and having its upper end terminatin'g within the filling neck 17 in the usual manner. The portion of the overflow pipe which is disposed exteriorly of the tank is designated by the numeral 40 and has its upper end flanged for engagement within a union 4Ithreaded upon the nipple 38 whereby the tube 40 may have communication with the tube 39 while insuring a tight oint at the point of connection.

In order to provide radiating surfaces whereby water may be cooled in its passage through the tubes from one tank to the other, I provide two fin carrying sections designated by the numerals 42 and 43 disposed at the front and rear of the body of tubes. Each fin section comprises a pair of spaced uprights 44 which have their lower ends resting upon the portions of the plate 34 extending beyond the sides of the lower tank, as clearly shown in Fig. 4. The fins 45 extend transversely of the tubes 14 and have their ends provided with lugs 46 secured upon the uprights 44 in any desired manner as for instance by means of rivets. The fins carried by the forward section 42 extend rearwardly to the center of the body of tubes 14 and the fins carried by the section 43 extend forwardly and terminate adjacent the center of the body of tubes in slightly spaced relation to the fins carried by the forward section. In order that the v and 43 are applied to the front and rearfaces of the body of tubes respectively with the lower ends of the uprights 44 resting upon the side edges of the plates 34. When the outer shell is then applied to the radiator proper, it will engage against the front of the uprights 44 of'the section 42 and against the rear of the uprights 44 of the sections 43 so that these fin sections willbe held in properly en a 'ng position in respect to the tubes an t e other portions of the radiator.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a radiator, the

parts of which may be readily and quickly assembled and held in clamped relation so that the use of solder will be avoided, the parts being also capable of ready disassembling so that defective tubes or .other 1 parts may be easily replaced in an expeditious manner.

While I have shown and described the preferred embodiment of my invention, it will of course be readily understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention nor the scope of the subjoined claim.

What is claimed is A radiator comprising upper and lower tanks, nipples extending from the lower and upper sidesv of said upper and lower tanks respectively, extensions within said nipples spaced from the walls thereof, said extensions being of greater length than said tubes disposed within the spaces between the 20 extensions and the walls of the nipples, resilient packing disposed within said spaces between the bottoms of the nipples and said flanges, and means for holding said tanks in clamping relation with respect to each other. 25

In testimony whereof I afiix my signature.
